Specification of Letters Patent'.

Application tiled March 5, 19111.

To all Awhom 'it may concern Be it known thatI, NORMAN R. Illinois, a citizen of the United States, residing at vPortland, in the county of Multnomah and State of Oregon, have inventednew and use ful Improvements in Vehicle-Tires, of which the following is a specification.

The invention relates to vehicle-tires, and more particularly to those tires for use on vehicles such as automobiles,and has for an object to provide a vehicle tire of the pneumatic type, which will minimize the danger of puncturesand blow-outs, and also iucreas'e the strength and durability of the usual outer .shoe generally employed in connection with tires of a pneumatic nature.

'The' invention further oomprehends the provision of a vehicle tire which will efficiently cushion the vehicle it 4is adapted to support, end which includes an inner nonexpansible tube, suitably reinforced between its face and the outer shoe, so that the said outer shoe will not be weakened when .air-is injected into the' inner tube, it being well known that in s large number of tires, now in use, the inflation of the inner tube results-in an expansion of the vouter shoe to an extent which materially weakens the shoe, thus exposing it to the cutting and puncturing actionA of any material or sub.

stance on the highway over which the tire is advanced, whereas if the outer shoe is not weakened in any manner, the molecules of rubber orother'material, forming the shoe, will be held closely together and thus prebeing cut or' otherwise punctured.

A still further embodiment of the invention resides in a tire in which the mentioned reinforcing, interposed between the inner tube and outer shoe, is' so arranged that it sent a surace'which will be less capable of will tend to deviate the pointed end of an article, which has penetrated the shoe, to an extent suiicient to prevent the penetration of the inner tube by the article, and wherein furthermore, if the said article should penetrate the inner tube, a sealing fluid carried within the inner shoe, will immediately plug the opening made by penetration and prevent tlu', escape of air from the tube.

In the further disclosure of the invention,

reference is to 'be had to the accompanying drawings, forming a part of this specification, 'm which similar characters of ref- PalZ-ented 0G17. 12, 191.5. serial no. .$22,654. I

erence denote corresponding parts inall the views, and in whic Figure 1 is -a fragmentary perspective view of my vehicle tire, having the outer shoe removed' therefrom -to show .the construction of the tube; Fig. 2 an enlarged vertical sectional viw of the complete tire;

Fig. Bis a' fragmentaryhorizontal sectional view, showing the'xnanner of constructing the,body of the tire; Fig. 4 is a fra entary vertical sectional View of a modi ed form of tire; part of the tire being shown' inside elevation; Fig. 5 is a' verticalV tra'nsterse sectional 'view 0f the-form o'f tire shownxin Fig. 4; Fig. 6 is a fragmentary perspective 'i numeral 11, and clearly shown in Fig. 1. It

will, of course be understood lthat the mucilaginousi substance is preferably of a gummy nature in order that v it'wille'ectively ifll the pores 'of the =innertube 10,' when applied thereto fas mentioned. L

wrapping 12 is now arranged to. encircle the vtube 10, and may consist of a cord 12,

as shown in Figs. l, 2, and 3, this cord being'fv woundaround the tube so that the convolu'- tions will fit closely together as indicated, the said cord being also adaptedlto be partially embedded in the layer 11- of muoilaginous substance,.sethatthe cord will rigidly adhereI to the face' or outer surface of the tube 10, and thus he prevented from cgeepin'g along the tube. The ,wrapping 1 is also coated with'a layer 14' crf'a mulaginous.substance, of the same nature as me heretofore mentioned layer for coating,

un the surface of the tube 10, the'said layer 14 being slightly thicker in order that the gummy andlikewise adhesive cement constitutingthe layer will till the interstices or grooves formed between adjacent convolutions of the cord 12. wound mon the *uhh 10 as stated, thus forming a smooth and sticky surface with the wrapping interposed between the layers 11 and 14 of 'the mentioned substance. I

A covering 15, preferably of rubber, eneircles the layer 14. and as will be readily understood, will rigidly adhere thereto, thusl binding the covering to the wrapping 12. The coveringis in turn partially encircled by a shoe 1G, of the usual type, and which includes opposed integral clencher fianges l?, having connection with a clencher rim 18. It will now he apparent that the body of the tire, consisting of the mentioned tube 10, the wrapping 12, covering' 15, and the layers 11 and 14, binding the wrapping to the tube and the covering to the wrapping, will be substantially inclosed in the shoe 16. and that the wrapping will not only prevent any undue bulging of the tube, when the same is inflated, but will also act as a protector for the tube to prevent the same from being punctured, while the provision of the ayer 11 of gummy cement will rigidly bind the Wrapping and tube together, the layer 14 of gummy cement being provided to fill the intersticcs between adjacent convolutions of the cord 12 and bind the covering 15 to the wrapping. as stated heretofore.

A cushion 19, preferably of a soft rubber, encircles the rim 18. 'as shown in Fig. 2, the said cushion being circular and interposed between the rim flanges 17. The cushion has a concave face 20, forming a seat for the body of the tire withthe covering lying against the said concave' surface in order that the cushion will perform its function, as will be hereinafter more fully explained. sheeting 21 is provided and has doubled portions thereof` lying alou the sides of the cushion 19, with a medialg'portion of the sheeting interposed between the underside of the cushion and the inner face of the rim 1S. The ends of the sheeting 21 engage the clencher flanges of the shoe 16 and lie between the said flanges and the rim. The sheeting 21. as provided, will prevent dust or dirt and other foreign matter from entering the shoe at its juncture with the rim 18. and will also efficiently protect the resilient. cushion 19 from moisture, the said cushion being conveniently provided with a series of apertures 22, which will greatly increase the cushioning effect of the cushion.

In Figs. 4 and 5 I disclosea modified form of my tire. and in which instance I employ a wrapping 23, of a woven nature with the wrapping interposed between the tube 10 and the covering 15. The wrapping consists more particularly of warp. threads 22?a and weft threads 23"' relativelyinterwoven as shown, thus forming a wrapping. which when interposed between the tube 10 and covering 15, with the layers 11 and 14 'another form of wrap ing. As'shown the wrapping is designate by the numeral 24,

and is of a tape or strip-like nature, the said wrapping being adapted to be wound onto the tube 10, w1ththe covering 15 inclosing the wrappingandlikewise'the tube, in the. same'manner as the constructions described heretofore. 'The layers 11 and 14 of mucilaginous substance, are of course, employed in connection withthe wrapping 24,' to secure the same rigidly tothe tube 10 and the coveringpl, thus preventing the wrapping from becoming displaced or creeping along the tube 10.

Still another form of wrapping 25 is disclosed'inVFig. 7, and in which'it will be seen that the same consists of a cord 25, wound around the lube 10, in one direction, and a second cord 25, wound around the cord 25l1 in the opposite direction, the cord 25 being held rigidlyon the tube 10 by the layer of mucilaginous substance 11, described heretofore,.and the cord 25b being held rigidly on the cord 25*'by tightlyfwinding the same on the cord 25", withtho layer of mucilaginous substance interposed'between the cord 25b and the covering 15, thus filling the interstiees between adiacent eonvolutions of the cord and rigidly binding the covering to the said cord.

I preferably iniect a suitable tire or puncture sealing Huid intothe tube 10, for the purpose of readily stopping what are commonlv known as pin-hole punctures. although it will also aid in plugging punctures of considerable size on account of the provision of the wrappinmencircling the tube. and which. if penetrated. adjacent the point of penetration of the tube. will receive a quantity of the sealing fluid from the inner tube. with the said fluid adapted to How through the Wrapping. andwhich. preferably made of cloth. will tend to stop the exit of air. upon becoming` saturated with the sealing Huid.

It will be understood that the modified forms of wrappings described and shown are adapted for use with the structure disclosed in Figs. 1 and 2. with any one of the said wrapnings adapted to. take the place of the particular form of wrapping used in connection with the structure. as shown, although I do not limit myself to the precise construction disclosed` but to the scope of the claimsy appended'hereto.

From the foregoingdescription. taken in connectionwith theyiews, it will be apparent that I provide a'tire, particularlv adaptable for heavy work. as on automobiles. and

ti (l Sii llt)

in which the chances of meeting with a puncture are greatly reduced, by'forming the `tire with a non-expansible inner tube which will prevent any bulging of the shoe Vand which, cooperating with the Wrapping lfore the intermediate wrapping is secured both to the inner tube and outer shoe and therefore .s not only bound to the tube and shoe but also acts as a means to bind the tube and shoe, thus preventing any creeping of the tube or Wrapping relatively to the shoe.

It will ofcourse be understood that the various component parts of the tire are suit ably vulcanized so that'the completed and finished tire will be a unitary structure in which the various coverings or mentioned layers of material will be relatively bound together by the vulcanizing process.

. Having described my invention, claim is;

1. A -tire comprising an inner non-expansible tube, a wrapping encircling the said tube, a layer of mucilaginous' substance interposed between the tube and the said wrapping and binding the wrapping to the tube,

what l j a covering encirclingl the said wrapping, a

layer-'of mucilaginous substance interposed between the covering and the wrapping, and

binding the covering tothe Wrapping, and a shoe inclosing the said covering, said tube,

wrapping and covering being relatively vulcanized.

2. A tire comprising an inner tube, a wrapping encircling the same, a coveringen circling the Wrapping, layers of mucilaginous' substance, one of said layers lyingv between the tube and the wrapping and the other lying between thev Wrapping and the said covering, and a shoe partially inclosing the covering and secured thereto.

3. A tire comprising an inner tube, a wrapping encircling the same, a covering for the Wrapping, means interposed between the tube and the said Wrapping and the wrapping and the said covering, for securiY of the Wrapping rigidly to the tube and tne covering rigidly to the wrapping, and a shoe partially inclosing the said covering.

4.111 a tire, an inner tube, a wrapping thereon, a covering for the wrapping, layers of mucilaginous substance, one of said layers lying` between the tube and wrapping and the other between the wrapping and covering, said tube and wrapping and wrapping and covering beingvulcanized to each other. Y
